Rocks occurring in narrow shear zones (<4 m wide) in a gabbro–anorthosite near Nusfjord, Flakstadøy, Lofoten, Norway, include Cl-enriched mineral assemblages, Cl-free mineral assemblages and eclogite-facies assemblages. Mineral equilibria calculations suggest that the different mineral assemblage...
